Remember you get what you pay for. Generally if you stick with name brand items you will be OK. Some people have different preferences but that is like the Ford vs. Chevy argument. Futaba, JR and Hitic all make good servos, gyros and electronics. OS and YS seem to be the engines of choice but the new TT .53 engine has had alot of good reviews. Flightpower and Thunder Power makes great batteries, I've had trouble puffing Align batteries. As for a charger/balancer I use the Accucycle elite and really like it.
